Hi @zperetz,

Sorry for unclear explanations. For Freenas 11.2, my workaround beside load drm.ko on loader.conf:

  • Install latest drm-kmod or drm-fbsd11.2-kmod on plex jail. We will get a lot of kernel modules file on /boot/modules related to kms and gpu firmware.
root@plex:~ # pkg info | grep drm
drm-fbsd11.2-kmod-4.11g20181210 DRM modules for the linuxkpi-based KMS components
drm-kmod-g20181126             Metaport of DRM modules for the linuxkpi-based KMS components
libdrm-2.4.96,1                Userspace interface to kernel Direct Rendering Module services

  • Copy above files to /boot/modules on Freenas host. It will overwrite some files. Maybe you can backup first the original freenas files. For older Intel GPU like mine, actually only need file debugfs.ko, drm.ko, i915kms.ko and linuxkpi-gplv2.ko. The rest files with prefix i915_ for new gpu firmware like broxton, skylake, kabylake and cannonlake.

  • on Freenas host, I also run command kldxref /boot/modules to update linker.hints file.

So, basically the point is replace all of kernel modules related with i915kms on Freenas host with new one.

Thanks
